In a particular crash test, a 1623 kg Mercedes SLS collides with a wall. The SLS hits the wall with a velocity of vi = 17.0 m/s and leaves the wall with a velocity of vf = -1.50 m/s. If the collision lasts for 0.25 s, find: (a) the impulse, and (b) the force of impact.

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.
